I'm not sure if this is a separate issue though...
On the raw file it hangs, and on ctrc-c I get this:

This is the change I made in swscale_internal.h:
#define VOF 4096
-#define VOFW 2048
+#define VOFW 4096
Slightly incrementing VOFW didn't help either, but I am not sure if it has to be
a multiple of 16 or a power of 2 or if there is a relation between VOF and VOFW,
so I might be perfectly normal that this doesn't work...
